Yeah, I don't think Lando should die in the final battle, I think Han should, Lando should die during the Sarlacc sequence. My idea (that just came to me) is this: They plant the explosives in the shield generator but they don't go off. If they don't blow up the shield, the fleet would be destroyed and everyone would die, so Han sacrifices himself and detonates the bomb manually. This could coincide with Luke hiding in the shadows refusing to fight Vader, and Luke could feel Han dying and it could be the trigger that makes him go after Vader, thus eliminating the need for Vader to talk about Luke's sister and thus enabling the removal of the whole stupid sister subplot.

But I understand it's probably pretty late now and it would also be hard to pull off (though not impossible).

i still think my best idea yet was that Leia was lukes sister but luke never tells her because obi-wan told him not to do so and all the jelousy is gone from Han it also makes vaders death more sad because he knows he has a daughter but leia still does not know her father....

Leia being shot in the arm triggers Lukes rage

It's all in my last act re-structure and I'm still sad about it getting voted a no :(

Got voted a solid no though... I wanted to make a more mature ROTJ but this is not my edit
